You can pan fry it and then use it however you want. I use the extra firm, drain it, slice about 1/2" thick, there should be about 8 pieces. Lay the rectangles on several paper towels or a tea towel and place another layer on top. Firmly press to get out the water.
In a pan, heat some oil (I like peanut or sesame but any is fine) over medium high heat, about a 7 on my gas range. Lay the slices in the pan and cook 3-4 minutes each side. I usually let them cook 2 min on the second side then add my sauce and cook the remaining 2. After you've done it a few times you will figure out if you like yours more or less crispy and adjust the cooking time and heat appropriately.
If I'm stir frying I cook the slices like above, remove from the pan, dice up and then cook with veggies and sauce for a few minutes before serving.
There are lots if sauce recipes out there and bottled sauces. Favorites of mine are a simple soy sauce/sugar/water glaze serving the hot tofu over baby greens, an orange juice glaze over rice and trader joes curry sauces with veggies and rice. I use sauce recipes from other tofu recipes but stickbtonthis cooking method.
Good luck! It takes a few tries to get the hang of it, but once you do it will be a quick, easy meal.
